1 About This Guide
This guide provides instructions on how to install your Cisco Catalyst Blade Switch 3120 for HP or
Cisco Catalyst Blade Switch 3020 for HP— referred to as the switch module—in the HP c-Class
BladeSystem and how to set up and configure your switch module. The HP c-Class BladeSystem—
referred to as the blade enclosure—supports up to eight Ethernet switch modules, which are installed
in the interconnect bays of the blade enclosure.
This guide also covers management options and troubleshooting help for the switch module.
For details on the numbers, types, and the location of the blade enclosure bays, for additional
information on the blade enclosure system, and for detailed port mapping information, see the
HP BladeSystem enclosure installation poster or the HP BladeSystem enclosure setup and installation
guide at http://www.hp.com/go/bladesystem/documentation.
For additional installation and configuration information about the switch module, see the Cisco
Catalyst Blade Switch 3000 Series for HP documentation on Cisco.com. For system requirements,
important notes, limitations, open and resolved caveats, and last-minute documentation updates about
the switch module, see the release notes, also on Cisco.com.
Note on WS-CBS3125G-S and WS-CBS3125X-S switch models:
• The WS-CBS3125G-S is the same product as the WS-CBS3120G-S.
• The WS-CBS3125X-S is the same product as the WS-CBS3120X-S.
The functionality and the performance of WS-CBS3125 switches are same as those of WS-CBS3120
switches. All Cisco Catalyst Blade Switch 3120/3125 for HP models are HP BladeSystem c-Class
compatible.
When you use the online publications, refer to the documents that match the Cisco IOS software
version that is running on the switch module. See the “Obtaining Documentation” section on
page 1-24 for more information about the switch module publications.
For translations of the warnings that appear in this publication and all safety and handling warnings
for this product, see the Regulatory Compliance and Safety Information for the Cisco Catalyst Blade
Switch 3000 Series for HP that accompanies this guide.
Before you continue with the installation, read the release notes for the blade enclosure. The release
notes are available on the HP support website at www.support.hp.com.
For warranty information about the switch module, see the Hardware Warranty Terms for the Cisco
Catalyst Blade Switch 3000 Series for HP on the documentation CD that ships with your switch
module.

2 Taking Out What You Need
Follow these steps:
1. Unpack and remove the switch module and the accessory kit from the shipping box.
2. Return the packing material to the shipping container, and save it for future use.
3. Verify that you have received the items shown on page 3. If any item is missing or damaged,
contact your Cisco representative or reseller for instructions.
If the switch modules are ordered with the blade enclosure, they are already installed. The unpacking
procedure for the switch module applies only if you order one separately. See the blade enclosure
documentation for the unpacking procedure for the HP equipment.

Cisco Switch Module Descriptions
These sections describe the switch modules:
• Cisco Catalyst Blade Switch 3120 for HP, page 4
• Cisco Catalyst Blade Switch 3020 for HP, page 6
The switch module is powered from the blade enclosure backplane. The switch module does not have
a fan. The blade enclosure provides temperature management.
The switch module connects internally to the management module through 100BASE-T Ethernet links.
You can manage the switch modules through the HP Onboard Administrator management module on
a management network that is isolated from other switch traffic. You can manage the switch module
through the RS-232 console port that uses an RJ-45 connector in the switch module front-panel. You
can also manage the switch module through any of the external uplink ports.
Cisco Catalyst Blade Switch 3120 for HP
The Cisco Catalyst Blade Switch 3120 for HP is a stackable, 25 to 27 Gigabit Ethernet port, Layer 3
switch module. The number of ports depends on the type of module installed in ports 19 to 22.
See Table 1 for a description of the switch module ports. See the release notes and the software
configuration guide for information about supported Layer 3 features. See the hardware installation
guide for detailed information about stacking the switch.
The Cisco Catalyst Blade Switch 3120 for HP has a 3120G and a 3120X model. Both are
stacking-capable. The initial setup procedure for both models is the same. For more information about
the features of each model, see the hardware installation guide and the software configuration guide
for the switch module.

port has an associated LED.
Table 1 Cisco Catalyst Blade Switch 3120 for HP Port Descriptions
Port Description
Ports 1 to 16 Internal Gigabit Ethernet 1000BASE-X downlink ports that connect to the
blade enclosure.
Ports 17 to 18 Internal cross-connection ports that you can use to connect to a second
switch in the blade enclosure through a backplane connector. You can
configure these ports by using the Cisco IOS CLI. However, if the blade
switches are stacked, these ports are disabled.
Ports 19 to 22 10-Gigabit Ethernet module slots for use with the Cisco TwinGig Converter
Modules and Cisco X2 transceiver modules.
Ports 23 to 26 External 10/100/1000BASE-T copper Gigabit Ethernet uplink ports that
support auto-MDIX and autonegotiation.
Internal 100BASE-T
Ethernet port
StackWise Plus ports Stacking cable ports.
Console port Switch module management port (RJ-45 connector).
The Ethernet management port (Fa0) is used only for switch module
management traffic, not for data traffic. It is connected to the
Onboard Administrator through the blade enclosure backplane connector.
Traffic to and from this port is isolated from the switch ports. This port
only supports autonegotiation with 100 Mb/s and full-duplex mode.
Cisco Catalyst Blade Switch 3020 for HP
The Cisco Catalyst Blade Switch 3020 for HP is a 24-Gigabit Ethernet port, Layer 2+ switch module.
Sixteen of the Gigabit Ethernet ports are internal 1000BASE-X downlink ports that connect to the
blade enclosure. The other eight Gigabit Ethernet ports are external uplink ports that provide
connections to other switches or routers. Uplink ports operate at 10/100/1000 M/ps if used as
copper-based ports and operate at 1000 M/ps if small form-factor pluggable (SFP) fiber-optic modules
are installed. See Table 2 for more detailed descriptions of the switch module ports.

Dual-purpose SFP module/RJ-45 copper Ethernet uplink ports. The SFP module
ports support only Cisco 1000BASE-SX fiber-optic modules.
By default, the switch module dynamically selects the interface type that first
links up. SFP modules have precedence if both SFP module and copper Ethernet
interface types are in link-up state. You can also specifically configure each port
for either copper Ethernet or SFP modules if you do not want to use
autodetection.
The copper Ethernet ports support automatic medium-dependent interface
crossover (auto-MDIX) and autonegotiation.
For information about configuring speed and duplex settings for a
dual-purpose uplink port, see the software configuration guide.

uplink ports. These ports can be configured for internal 1000BASE-X
cross-connection with a corresponding switch module. When ports 23x and
24x are in external operation mode, they support auto-MDIX and
autonegotiation. The default is external operation mode.
The Ethernet management port (Fa0) is used only for switch module
management traffic, not for data traffic. It is connected to the Onboard
Administrator through the blade enclosure backplane connector.
